我正在尝试根据列表中的位置匹配列表中的对象。对于特定CSV,列表中的位置始终相同,但会因客户端而异。
我有一个包含5个客户端的字典,以及CSV中包含数据的列:
d = {'Client1':{
'file1DataPositions':[1,3,5,6,9],
'file2DataPositions':[2,4,5,7,8]},
'Client2':{
'file1DataPositions':[3,4,5,6,7],
'file2DataPositions':[1,5,7,8,9]},
'Client3':{
'file1DataPositions':[2,6,7,8,9],
'file2DataPositions':[1,2,7,8,9]},
'Client4':{
'file1DataPositions':[2,3,4,6,6],
'file2DataPositions':[1,3,5,7,9]},
'Client5':{
'file1DataPositions':[2,4,6,8,9],
'file2DataPositions':[5,6,7,8,9]}
}
我有一个填充的嵌入式列表(已解析的CSV):
l = [['data1','123','ABC','CompanyName','Employee1','15','123 Notareallstreet','Bobs Trucks','Newyork'],
['data2','456','DEF','CompanyName','Employee2','15','123 Notareallstreet','Bobs Trucks','Newyork'],
['data3','789','GHI','CompanyName','Employee3','15','123 Notareallstreet','Bobs Trucks','Newyork'],
['data4','012','JKL','CompanyName','Employee4','15','123 Notareallstreet','Bobs Trucks','Newyork']]
根据嵌入列表中索引的位置,我想查看索引是否匹配:
def iterationTest():
for item in l:
for lis in item:
if lis.index() == d['Client1']['file1DataPositions']:
print('Match Found')
iterationTest()
当我运行它时,我得到一个:" index()至少需要1个参数(0给定)"错误。
有没有正确的方法来做我想做的事情?
答案 0 :(得分:1)
使用enumerate()
:
def iterationTest():
for item in l:
for idx, lis in enumerate(item):
if idx in d['Client1']['file1DataPositions']:
print('Match Found')
iterationTest()
这将迭代lis
中的每个item
,并且在循环的每个阶段,它都会提供对lis
及其索引idx
(您的访问权限)的访问权限用于比较)。

你到底想要做什么?你在寻找列表索引吗? 我猜你正试图这样做:
d = {'Client1':{
'file1DataPositions':[1,3,5,6,9],
'file2DataPositions':[2,4,5,7,8]},
'Client2':{
'file1DataPositions':[3,4,5,6,7],
'file2DataPositions':[1,5,7,8,9]},
'Client3':{
'file1DataPositions':[2,6,7,8,9],
'file2DataPositions':[1,2,7,8,9]},
'Client4':{
'file1DataPositions':[2,3,4,6,6],
'file2DataPositions':[1,3,5,7,9]},
'Client5':{
'file1DataPositions':[2,4,6,8,9],
'file2DataPositions':[5,6,7,8,9]}
}
l = [['data1','123','ABC','CompanyName','Employee1','15','123 Notareallstreet','Bobs Trucks','Newyork'],
['data2','456','DEF','CompanyName','Employee2','15','123 Notareallstreet','Bobs Trucks','Newyork'],
['data3','789','GHI','CompanyName','Employee3','15','123 Notareallstreet','Bobs Trucks','Newyork'],
['data4','012','JKL','CompanyName','Employee4','15','123 Notareallstreet','Bobs Trucks','Newyork']]
def iterationTest(Preview=True):
for clientKey , clientValue in d.iteritems():
for dataKey, dataValue in clientValue.iteritems():
if Preview:
print "Data Position: %s"%dataKey
for eachnum in dataValue:
if eachnum <= len(l[0])-1:
if Preview:
print "Match Number: %s"%eachnum
print "Number Value: %s"%l[0][eachnum]
print "------------------------------"
if Preview:
print "=============================="
iterationTest()
